Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
2. The method of claim 1, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
This invention relates to wireless communication systems, specifically methods for managing timing offsets in data transmission and reception. The problem addressed is the need for precise synchronization between transmitting and receiving devices to ensure reliable data delivery, particularly in systems using hybrid automatic repeat request (HARQ) protocols or subframe-based scheduling. The invention provides a method to adjust timing offsets to optimize communication efficiency and reduce errors. The method involves determining an offset value to align transmission and reception timelines. The offset can be a subframe offset, a HARQ offset, or a time offset, depending on the system requirements. A subframe offset adjusts the timing of data transmission within a subframe, a HARQ offset ensures proper spacing between retransmissions, and a time offset synchronizes communication across different time intervals. The method dynamically selects the appropriate offset type based on system conditions, such as channel quality or latency requirements, to improve performance. This approach minimizes delays, reduces packet loss, and enhances overall system throughput by ensuring that data is transmitted and received at the correct times. The invention is particularly useful in 5G and other advanced wireless networks where precise timing is critical for efficient operation.
5. The method of claim 4, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
This invention relates to wireless communication systems, specifically to methods for managing timing offsets in data transmission and reception. The problem addressed is the need for precise synchronization between transmitting and receiving devices to ensure reliable data delivery, particularly in systems using hybrid automatic repeat request (HARQ) protocols or subframe-based scheduling. The method involves determining an offset value to adjust the timing of data transmission or reception. The offset can be a subframe offset, a HARQ offset, or a time offset. A subframe offset adjusts the timing of data transmission or reception relative to predefined subframe boundaries in a wireless frame structure. A HARQ offset adjusts the timing of acknowledgment or retransmission signals to account for processing delays or propagation delays. A time offset provides a general timing adjustment to synchronize data transmission or reception with other network operations. The method may also include selecting the type of offset based on system requirements, such as the need for fine-grained timing control or compatibility with specific communication protocols. The offset is applied to transmission or reception timing to ensure proper alignment with expected data arrival or departure times, reducing errors and improving communication efficiency. This approach enhances synchronization in wireless networks, particularly in scenarios where precise timing is critical for reliable data exchange.
8. The apparatus of claim 7, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
9. The apparatus of claim 7, wherein the processor is configured to receive a message including the offset via a Physical Downlink Control Channel (PDCCH) or Enhanced PDCCH (EPDCCH).
11. The apparatus of claim 10, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
This invention relates to wireless communication systems, specifically to apparatuses and methods for managing timing offsets in communication protocols. The problem addressed involves ensuring proper synchronization and timing alignment between devices in a network, particularly in scenarios where different types of offsets—such as subframe offsets, HARQ (Hybrid Automatic Repeat Request) offsets, or general time offsets—are used to coordinate transmissions and receptions. These offsets are critical for maintaining reliable communication, reducing interference, and optimizing resource utilization in wireless networks. The apparatus includes a processor configured to determine and apply an offset to adjust timing for communication operations. The offset can be a subframe offset, which aligns the timing of subframes in a communication frame structure, a HARQ offset, which adjusts the timing for retransmission requests and acknowledgments, or a time offset, which generally synchronizes communication events. The processor may also generate control signals to configure communication parameters based on the determined offset, ensuring that transmissions and receptions are properly timed. Additionally, the apparatus may include a memory to store offset values and a transceiver to handle the actual communication with other devices in the network. By dynamically adjusting these offsets, the invention improves synchronization, reduces latency, and enhances overall communication efficiency in wireless systems. This is particularly useful in scenarios where devices operate under varying conditions or when different timing requirements must be met for different communication protocols.
12. The apparatus of claim 10, wherein the processor is configured to transmit a message including the offset via a Physical Downlink Control Channel (PDCCH) or Enhanced PDCCH (EPDCCH).
14. The non-transitory computer readable medium of claim 13, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
15. The non-transitory computer readable medium of claim 13, wherein the processor is configured to receive a message including the offset via a Physical Downlink Control Channel (PDCCH) or Enhanced PDCCH (EPDCCH).
This invention relates to wireless communication systems, specifically to methods for managing data transmission offsets in downlink control channels. The problem addressed is the need for efficient and reliable communication of timing offsets between a base station and user equipment (UE) to optimize data transmission scheduling and resource allocation. The invention involves a non-transitory computer-readable medium storing instructions that, when executed by a processor, configure the processor to receive a message containing a timing offset via a Physical Downlink Control Channel (PDCCH) or Enhanced PDCCH (EPDCCH). The offset is used to adjust the timing of data transmissions, ensuring synchronization between the base station and UE. The processor may also determine the offset based on predefined criteria, such as signal quality, interference levels, or network load, and apply the offset to subsequent transmissions to improve efficiency and reduce latency. The system may further include mechanisms to dynamically update the offset in response to changing network conditions, ensuring optimal performance. This approach enhances reliability and reduces errors in data transmission by aligning timing parameters across the network.
17. The non-transitory computer readable medium of claim 16, wherein the offset is a subframe offset, a HARQ offset, or a time offset.
18. The non-transitory computer readable medium of claim 16, wherein the processor is configured to transmit a message including the offset via a Physical Downlink Control Channel (PDCCH) or Enhanced PDCCH (EPDCCH).
